cnnm-snranarme DEVICE.

p p are, theprovisinn in 'a merchantable form of a cream separating device which may be drawn u tion and devoid neath the cream after it has collected upon the milk, permitting the creamto be poured from the milk in a separate and dis tinct mass A device of the class described should be inexpensive to manufacture, facile in operaof complicated parts; it should be capable of manipulation without mtermingling the milkand the cream which has collected; and these ends aresought to be effected in my invention.

With these objects in view, together with others which a perusal of .this specification will reveal to those skilled in the art, the invention consists in the novel construction and arrangement of parts hereinafter described, delineated inthe accompanying drawings and particularly pointed out in the appended claims, it being understood thatvarious changes in the form, propor tions, size and minor details of the structure may be made without'departing from the spirit .or sacrificing any'of the advantages of the invention. I

Similar numerals of reference are em-' ployed to indicate corresponding parts throughout the several figures of the drawings.

In the accompanying drawings, Figure 1 shows in perspective, the cream separating device and the receptacle cover; Fig. 2 is a vertical section through the diameter of the milk receptacle, showing two positions of the wings 1; Fig. 3 isan elevation of a modified form of In y invention.

My invention is intended to be used in connection with amilk receptacle 5 which may be of any shape; it is shown in the common cylindrical form and I shall describe my invention as adapted for use in cylindrical vessels, although another form might be employed in particular instances. thus constructed, my cream separating device consists of a circular plate, bisected Specification of Letters Patent. Application filed July 10, 1908. Serial No. 42,940.

. I have shown it their ends pivotally Patented Sept. 29, 1908.

diametrically into the wings 1. Upon their straight inner edges, the wings 1 are pivotally mounted upon the transverse axle 3 and adapted to be rocked upward and downward upon said axle. The mode of attaching the wings 1 to the axle 3 may be varied throu h all of the common methods of the art a apted to promote a union'of the sort shown and described.

In practice I have found it convenient to fashion the wings 1 from metallic sheets, providing strips 2, projecting from the straight inner edges and adapted to be wrapped about the axle 3, the said strips 2 being integral with-the wings 1, or soldered or riveted thereto. The periphery of the wings 1 should be resilient in order to form a milk-tight joint between the periphery of the wings 1 and the inner surface of the receptacle 5. ring 4 may be attached to the wings 1, and pern'iitted to project laterally to engage the inner surface of the receptacle?) as aforesaid.

The device may be lowered and raised by means of the guide-rod 7 which should be terminally connected with the axle 3. As

shown, the guide-rod 7 may be integral with the axle 3 and in this case, one end of the axle 3 is bent inwardly upon itself as shown at 6, and then flexed vertically upward to form the guide-rod 7. Into the upper end of the guide-rod 7 may be bent a hand-hold S.- It is advantageous to have the guide-rod 7 rise vertically above the center of the circle formed by the periphery of the wings 1, and so disposed.

My invention should include means for rocking the wings 1 upwardly and downward upon the'axle 3 and to this end, I have provided the operating-rod 9, terminating at its upper end in the hand-hold 10, similar in shape to the hand-hold 8 and adapted "to be grasped simultaneously therewith. The operating-rod 9 is slidably mounted upon the guide-rod 7 and terminates at its lower end in means adapted to form an operative connection between the rod 9 and the wings In the embodiment of my invention selected as the subject of illustration, I have attached to the bottom of the operating-rod 9, the cross-head 11. The cross-head 11 is connected with the upper surface .of the wings 1 by the inflexible members 12, having mounted in the crosshead 11 and the wings 1. The ends of the cross-head 11 may be pierced and rings 13 To effect this end, a resilientplace.

.. receptacle in mounted upon the upper surface of the wings 1. to term attaching points for the intlexible members 12. It desired a cover 14 may be provided, centrally pierced to serve as a guide tor the rod 7, an excision 15 furnishing ameans ,l'or pouring the cream 16 above the wings I, from the receptacle 5.

In the modified l'orul shown in Fig. 3, the guide-rod is attached. to the receptacle 5, The attachment may be rigid, or, as shown. adjustable, any well-kimwn means adapted to the required end being selected. In the term chosen, the tlnnnbscrcw 17 furnishes the meanst'o adjustment.

It will be seen that in both forms, the guide-rod 7 is attached, through the member (3 and theaxle 3, to the inner edges o tne wings 1, and that this constriuztioir together with the method employed for connecting the operating-rod t) with the wings 1,'serves to distribute the strain upon the wings 1, whenthe latter are rocked upon the axle 3, or moved bodily upwar l or downimrd.

In practical operation the hand-holds S and 10 are separated vertically, the operating-Hal 9 forced downward, and the wings, rocked downward upon the axle The wings 1 are then inserted in the receptacle 5 and lowered to the bottom of the receptacle, their positions relative to each other being uuchanged. Milk is then poured into the receptacle 5 and the cover .14 seated in its hen the cream 16 has risen upon the milk, the device isgently raised by the hand-hold 8, until the wings l are directly beneath the cream. The hand-hold 10 is then grasped, the operating-rod 9 drawn upward, the wings I rocked upward and theirflperiphery brought into close, milktight contact with the inner surface of the milk receptacle 5. The receptacle .5 may then be tilted and the cream permitted to flow out through the excision 15. The wings 1 being rocked downward, the milk may be poured into another receptacle and the cream separating device removed from the receptacle 5 for'cleansiu In the case of the modifiedform shown in Fig. 3, the guide-rod 7 may beset vertically to bring the wings 1 into a position o-perative to cut off an average cream volume for a fixed quantity of milk. In this case, a fixed quantity of milk being placed in the each instance, the-device requires no further manipulation than the upwardand downward rocking of the wings Having thus described my invention, my claims are as follows;

.ent outer edge, pivotally nally connected with the axle; m 1115 for rocking the wings, mounted upon the guiderod. 7

2. A. device of the class described con'iprising a transverse axle; wings having av resilimounted upon the axl i; a guide-rod terminally connected with the axle; means for rocking the wings, n'iounted upon the guide-rod.

3. A device of the class (ltSCl'lbtBtl comprising a transverse axle; wings pivotally mounted upon the axle; a resilient ring projecting laterally tromthe outer edge of the wings: a guide-rod terminally connected with the axle: means for rocking the wings,

mounted upon the guide-rod.

4. A device of the class described comprising a transverse axle having one of its ends bent inward upon itselt and liexed into a. straight vertical arm; wings pivotally mounted upon the axle; means for rocking the wings.

5. In a. device of the class described. a. transverse axle; a guide-rod terminally conwings pivotally mounted upon the axle: an operating rod mounted uponthe guided-ed, adapted to rock the wings.

6. In a device of the class described, a transverse axle; a guide-rod terminally con nected with the transverse axle; wings pivotally mounted upon the axle; an operating rod slidably mounted upon the guide-rod, adapted to rock the wings upon the axle:

7. In a device of the class described, a transverse axle; wings pivotally mounted upon the axle; a guide-rod terminally connected with the axle; an operating rod slidably mounted upon the gi'iide-rod, means for connecting the operating-rod with the wings.

8. In a device of the class described, a transverse axle; wings pivotally mounted upon .the axle; a guide-rod terminallv connected with the axle; an operating-rod slidably mounted upon the guide-rod; inflexible members pivotally connecting the lower end of the operating rod with the upper surface of the wings.

In testimony that I claim the foregoing as my own, I have hereto aflixcd my signature in the presence of two witnesses.
